Nick, I don't find blonde copilots to be any better at flying than brunettes or redheads. I do find that female copilots generally smell & look better than males, though.
Personally, I'll take range & speed over Cat A every day. If the fuel gets used up before you finish the ILS, Cat A means nothing, & if you can't load on enough fuel to get to the destination, Cat A means nothing. I'll take range, speed, EGPWS, TCAS, etc and take my chances with OEI ops.
